Answer:

6 cups of yellow paint and 9 cups of red paint are required for 3 batches of orange paint.

Step-by-step explanation:

Consider the provided information.

A particular shade of orange paint has 2 cups of yellow  paint for every 3 cups of red paint.

We need to find the numbers of cups of yellow and red paint  needed for 3 batches of orange paint.

For one batches of orange paint we need 2 cups of yellow and 3 cups of red.

So for 3 batches of orange paint we need:

2×3 = 6 cups of yellow paint.

3×3 = 9 cups of red paint.

The required number line is shown below.

Answer: The p-value is 0.154.

Step-by-step explanation:

Since we have given that

We claim that

Null hypothesis :

H_0:\mu=20

Alternate hypothesis :

H_1:\mu

Population mean = 20 hours

Sample mean = 18.5 hours

Sample standard deviation = 4.3 hours

Sample size n = 35

So, test statistic would be

z=\dfrac{\bar{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\z=\dfrac{18.5-20}{\dfrac{4.3}{\sqrt{35}}}\\\\z=\dfrac{-1.5}{0.726}\\\\z=-2.066

So, the  p value would be 0.154.

Hence, the p-value is 0.154.

In parallelogram PQRS, PQ =4x+28, QR=x+31, RS = 10X+4. Which of the
Doss [256]

Answer:

44

Step-by-step explanation:

1) we know that opposite sides of a parallelogram are congruent so

4x+28=10x+4

2) subtract 4 on both sides

4x+24=10x

3)subtract 4x on both sides

24=6x

4)divide by 6 on both sides

4=x

5)substitute for x

length of RS =10(4)+4

length of RD=44
